Description

This module exploits a stack-based buffer overflow vulnerability against Ayukov NFTPD FTP Client 2.0 and earlier. By responding with a long string of data for the SYST request, it is possible to cause a denail-of-service condition on the FTP client, or arbitrary remote code exeuction under the context of the user if successfully exploited.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/ftp/ayukov_nftp
msf exploit(ayukov_nftp) > show targets
    ...targets...
msf exploit(ayukov_nftp) > set TARGET < target-id >
msf exploit(ayukov_nftp) > show options
    ...show and set options...
msf exploit(ayukov_nftp) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
